Photosynthesis

Front

What is the primary function of photosynthesis?

Back

The primary function of photosynthesis is to convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

Where do light-dependent reactions occur in the chloroplast?

Back

Light-dependent reactions occur in the thylakoid membranes of the chloroplast.

Front

What is produced during the light-dependent reactions of photosynthesis?

Back

The light-dependent reactions produce ATP, NADPH, and oxygen.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the pigment that absorbs light energy, primarily in the blue and red wavelengths, and is essential for photosynthesis.

Front

What are the reactants required for photosynthesis?

Back

The reactants required for photosynthesis are light energy, water (H2O), and carbon dioxide (CO2).

Front

What is the main product of the light-independent reactions (Calvin cycle)?

Back

The main product of the light-independent reactions is glucose (C6H12O6).

Front

Where do light-independent reactions occur in the chloroplast?

Back

Light-independent reactions occur in the stroma of the chloroplast.

Front

What is the significance of the oxygen produced during photosynthesis?

Back

The oxygen produced during photosynthesis is released into the atmosphere and is essential for the respiration of most living organisms.

Front

How does carbon dioxide enter the leaves of plants?

Back

Carbon dioxide enters the leaves of plants through small openings called stomata.
